My invention relates to an improvement in the air intake regulators of carbureters; and the objects of my invention are; first; to provide an air intake regulator for oarbu reters which shall be automatic for all speeds and for allcondition's ofload on the engine; second; to provide an air intake regulator for carburetors which will permit of greater flexibility in the throttle control of explosive hydrocarbon motors than has been possible prior to my invention. I attain these objects by the mechanism illustrated in the accompanying drawings, in which Flgure 1 is a transverse section elevation of my device; and Fig. 2 is a longitudinal I 25 section elevation ofmy device.

Similar letters refer to similar parts throughout the several views. Fi 1 is a section taken on the plane X A is a pipe leading to the mixing chamber. Bis aT pipe 0 eni'ng into A. C is a spider at the end of D is a circular holein the spider B. S is a set screw. Fig. 2, is a longitudinal section elevation taken on the plane a 6 (Fig.1). A is'the pipe leading to the mixing chamber. B is the T pipe 0 ening into A. C is the spider l3. R is a light rod which plays freely in the hole D. K is a taper cap over The end of this taper cap is. com osed of a s ider C, with a hole D through w rich the re R plays freely. Rigidly attached to the rod 1t and at right angles thereto, are two light circular diastructure F R-G is hragms F and G.- The die hragm G is 'aphragm F.

B, and the diaphragm G fits loosely in the ,taper head K. The ends of the rod R-fit loosely in the holes D and D. The entire cc to move to a limited degreein a. longituihnal direction with refer ence to the structure C B C K. S is a set screw to. limit the backward motion of the structure F R G.

When the device is in-use it must be so placed that the rod R is approximately perpendicular to the horizontal with the taper cap K at the bottom and the spider C at the ihe operation of the device is as follows: The force of gravity acting on the structure F R G brings the dia hragm G into contact with the inner face of the taper ca K. As soon as the engine starts, a is induced in the tubes A BJM B. This partial vacuum in B causes the normal atmospheric ressure to become actively operative on the ower face of the diaphragm G'and on the 11 per face of diaphragm F. It is obvious t rat if the area of the diaphragm F exactly equaled the area of the diaphragm G. the structure F ll G would remain unmoved in equilibrium. phragm G is greater than the area of d'ia phragm F, there is a greater total pressure exerted 'on the lower-lace of diaphragm G.

artia vacuum But as the area 'of diaupward in the tube B. This upward motion of the structure F R G leaves an annular side of the taper cap K; and this annular space admits more air to the tubes B and A,

and feeds more air to the carbureter.

The faster the engine runs, the greater the partial vacuum in the tubes A and B, and the, more the diaphragm G is lifted from the inside face of the taper head K, and the more air is admitted to the carbureter. On the other hand, the slower the engine 'runs, the less the partial vacuum in the tubes A and B, and the less the diaphragm G is liftedfrom the inside face of the taper head K, and the less air is admitted to the carbureter.

I claim as my invention.
